About this part

Product Details

If you're looking to add significant horsepower to your vehicle, this Nitrous Express 4150 4-BBL/Alcohol Nitrous Kit is designed to do just that. This system is built for carbureted applications, specifically those using a 4150-style carburetor, and can be tuned to add anywhere from 100 to 500 horsepower. It's a popular choice for racers who need a substantial power boost for track use.

What sets this kit apart is its spraybarless plate design. Instead of traditional spray bars that can sometimes cause issues with airflow distribution or get damaged, this advanced plate technology ensures a more consistent and even distribution of the nitrous and fuel mixture. This leads to better atomization and more reliable performance, especially when you're pushing your engine hard. The kit comes with everything you need to get started, including limited lifetime guaranteed Lightning solenoids, a heavy-duty 40-amp relay, a 15lb nitrous bottle, stainless steel bottle brackets, and an extra-long supply line for flexible installation.

This system is specifically available for alcohol-based fuel systems, offering a unique advantage for certain racing applications. Please note that this kit is not CARB approved and cannot be shipped to California. It's important to consult your local regulations and ensure this system is legal for use in your area.
